Texting is the preferred method of communication among young people, with 72% of teenagers saying they text regularly and one in three sending more than a hundred texts per day. Unfortunately, however, very few youngsters seem able to communicate using grammatically correct sentences. They seem to think it 'gr8' that correct spelling is no longer considered necessary. Many local employers have complained that school-leavers have no idea how to communicate appropriately, whether face-to-face or in business letters. Many written job applications are phrased so poorly that they go straight in the bin. Mobile phones were banned in my daughter's school last year, a move which has proved fully justified. Since then test scores in English have improved. All schools need to introduce a similar ban. Which one of the following best expresses the flaw in the above argument?

A It makes a false statistical comparison between the 72% of teenagers who merely text regularly and those who send more than a hundred texts in a day.

B It assumes that, because test scores improved after the ban on mobile phones, the improvement was due to the ban.

C The argument rests on the assumption that communicating by text is inappropriate.

D Its conclusion, that communicating by text is inappropriate, merely restates one of the reasons given in support of the argument.

E It assumes that correct spelling is a necessary requirement for gaining employment.
